Le bioéthanol est un carburant liquide produit à partir de biomasse végétale via un certain nombre de processus chimiques/biologiques . Il peut être ajouté à l’essence à hauteur de 10-15% sans modifier la structure des moteurs à combustion. La directive 2003/30/EC de l’Union Européenne prévoit pour 2010 un remplacement de 5,75% et de 20% pour 2020. Mais en réalité fin 2006 on en était à 1%, bien loin des 5,75%. Pour palier à ce retard, le 7ème PCRD a prévu un budget de 17.000.000 d’Euro/an à des projets de recherche sur les énergies renouvelables. Les avantages de la promotion d’une technologie de transformation biomasse-éthanol incluent la sécurité énergétique nationale, la réduction des émissions de gaz à effet de serre, l’utilisation de ressources renouvelables, le bénéfice économique avec création d’emploi, la mise en place d’une technologie microbienne nouvelle respectueuse de l’environnement . En 2006 il y avait cinq pays principaux producteurs d’éthanol (en millions de litres) : USA (18,3), Brésil (16,9), Chine (3,8), Inde (1,9) et France (1,1). Pour ces pays l’incorporation de bioéthanol dans les carburant a été de 24% pour le Brésil et de 10% pour les USA, Canada, Colombie, Thaillande alors que pour

Ernesto Favela-Torres
Liriasa « Technologie de saccharification de la jacinthe d’eau pour l’obtention de produits à haute valeur ajoutée et son utilisation potentielle pour la production de biocarburants », est un projet Foncicyt-Union Européenne, dans lequel participe l’équipe d'Écologie Microbienne et Biotechnologies de l’IMEP avec TEMA, un groupe industriel mexicain, et quatre équipes de recherches (UAM-I du Mexique, IRD du France, UPP du Pachuca, CIB-CSIC d'Espagne). Dans ce projet, la production des enzymes fongique sera développée en utilisant des champignons filamenteux mésophiles et thermophiles de la collection de l’IMEP-IRD cultivés en milieu solide sur la biomasse de la jacinthe d’eau. L’atelier « Jacinthe d’eau » qui aura lieu les 24 et 25 août à Avignon France, dans le cadre du Congrès Européen de Restauration (SER-Avignon 2010) permettra aux différentes équipes de présenter l’avance de leurs travaux de recherche au bout de la première année du projet. En particulier les équipes de
La jacinthe d’eau, plante invasive et usages de sa biomasse à travers le monde
Sevastianos Roussos, Isabelle Gaime-Perraud, Oswaldo Guzman-Lopez, Mustapha Kabiri, Gladys. G. Pérez-Morales, Teresa Torres-Mancera, Gerardo Saucedo-Castaneda, Ernesto Favela-Torres
La jacinthe d'eau (Eichhornia crassipes) est une plante flottante d'origine tropicale qui se caractérise avec une forte reproduction et une grande adaptation à des milieux aquatiques comme les rivières et les lacs et de ce fait, elle est considérée comme une plante invasive. E. crassipes cause des problèmes économiques et écologiques comme, la perte d'eau induite pour la forte évapotranspiration, des soucies au transport fluvial, des arrêts des générateurs hydro-électriques dans les barrages et la diminution de la biodiversité dans les écosystèmes aquatiques. S’agissant d’une plante, sa composition est essentiellement faite la cellulose (29%), hémicellulose 20%), lignine (14%) et des minéraux (16%) selon Zhou et al. (2009). Comme elle a un rôle de filtre, elle accumule des concentrations élevées en éléments minéraux (Pb, Mercure etc). présents dans l’eau (Mahamadi et Nharingo, 2010). Grâce à cette composition lignocellulosique, la biomasse de la jacinthe constitue un matériau adapté pour la culture des champignons filamenteux en milieu solide pour la production d’une multitude d’usage : champignons comestibles (Pleurotes, Shitake), de biopesticides, d’enzymes pour la saccharification de la biomasse et la production de biocarburants (objet du présent projet). Traditionnellement dans les pays tropicaux, la jacinthe est utilisée pour fabriquer des cordages, en vannerie pour le tissage des nattes, des paniers, et divers objets domestiques. Au Mexique
Screening for xylanases strains producers on agar plates and solid state fermentation
Ramirez-Coronel Ascencion
The selection of fungal strains with high levels of saccharifying enzyme production in the early stages is very important to development saccharification process of any lignocellulosic material. The aim of this work was to evaluate 54 strains of filamentous fungi from different microbial collections of Mexican institutions for xylanase production. The power index (PI), which is defined as the diameter halo of hydrolysis between the diameter of the colony developed in Petri dish, was evaluated. The halo was revealed at the end of cultivation with iodine. Of the 54 strains, 14 strains were selected to evaluate their production of xylanases in solid state fermentation with agrolite as inert support impregnated with Pontecorvo medium enriched with birch wood xylan as inducer of xylanase synthesis. Xylanase activity (UI/gms) was determined in enzyme extracts produced in FMS. For the 14 selected strains, the enzyme activity values obtained in FMS were plotted as a function of the IP values obtained in the bioassays in Petri dishes. This yield a regression coefficient (r2) of 0.83, which proves a good correlation between enzyme activity values obtained by fermentation in solid medium and the Power Index obtained in Petri dish bioassays. This shows the validity of the bioassay method used for the screening selection of filamentous fungal strains producers of xylanases in FMS. The highest values of xylanase activity were 172.8 UI/gms and 185.6 UI/ gms for the strains of Penicillium sp and Trichoderma sp respectively.

Water hyacinth (WH) is an aquatic weed common which is very frequently found ib subtropics and tropics zones and causing ecological and socioeconomic problems. WH is an abundant biomass source composed of cellulose (18% dry weight) and hemicellulose (30–55% dry weight). This plant material could be used as substrate for production of hydrolytic enzymes ectinase, xylanase and cellulose activity Cellulose represents the major constituent of cell wall polysaccharides and consists of a linear polymer of ?-1,4-linked d-glucose residues. The cellulose polymers are present as ordered structures (fibers), and their main function is to ensure the rigidity of the plant cell wall. Hemicelluloses are more heterogeneous polysaccharides and are the second most abundant organic structure in the plant cell wall. Recently there is a renew interest in microbial and enzymatic conversion of renewable materials as WH into useful products, such as feed, chemicals and energy. The objective of this work was to test a rapid method to screening of fungal isolates (UAM-IRD-IMEP collection) taken into account the hydrolytic enzyme activities (pectinase, xylanase).Screeing of strains was performed in Petri dishes using a basal mineral medium containing three different sources of polysaccharides: birchwood xylan, carboxymethyl cellulose or water hyacinth biomass. Lugol and blue cotton were used to show the clearing zones of different carbon sources used. A number of 105 strains were screened and selected according to the production of cellulases and xylanases. Selected strain could be used to obtain fermentable sugars enzymatic hydrolyis from WH.

Water hyacinth (Eichhornia crassipes) biomass is suitable for bio-ethanol production. Cell wall composition of this invasive plant is about 48% hemicellulose, 18% cellulose, 3.5% lignin. Enzymatic hydrolysis of this polysaccharides is catalyzed by cellulases and hemicellulases (such as xylanase) that are produced by a wide range of microorganisms particularly fungi. A power index was calculated as the ratio of clearing zones due to enzymatic activity and diameter of colony of fungi. Characterization of mesophilic and thermophilic fungal strains belonging to UAM-IRD-IMEP collection was performed in Petri dishes. Strains were characterized by using normalized values of power index and the radial growth rate. Assays were realized by using a defined broth (Medium Roussos) added with 3 different substrates (birchwood xylan, carboxymethylcellulose and water hyacinth biomass). A culture on PDA (Potato Dextrose Agar) was used as reference. Results were plotted on a Cartesian plot. Thus, filamentous fungi strains were classified into four quadrants corresponding to their different phenotypes. A number of 20 strains were selected due to its high growth rate and the higher clearing zone due to hydrolyze the substrates (cellulose, hemicellulose or water hyacinth biomass). Results will be useful for further studies to produce fermentable sugars form water hyacinth biomass.

Fungal strains produce a wide range of hydrolytic enzymes (cellulases and hemicellulases, laccases, etc.). Mesophilic fungi as Aspergillus and Trichoderma are used for the production of xylanase and cellulase. Recently, a renew attention has been put into the isolation of thermophilic fungi producing hydrolytic enzymes including Chaetomium, Humicola, Myceliophthora, Paecylomyces, Talaromyces, Thermomyces and Thermoascus. The aim of this work was to select mesophilic and thermophilic fungal strains (UAM-IRD-IMEP collection) according to the capacity of producing hydrolytic enzymes and radial growth rate. Results shown differences between genus of fungi. Mesophilic and thermophilic strains were described according to their radial growth rate and hydrolysis index of using cellulase, hemicellulose and water hyacinth biomass as substrate. A hydrolysis index was calculated as the ratio of clearing zones due to enzymatic activity and diameter of colony of fungi and divided by the culture time. Penicillium and Aspergillus strains presented a higher hydrolytic index but the culture is limited by a low radial growth rate. The higher radial growth rates and hydrolysis index were observed for the strains belonging to genus Trichoderma and Myceliophthora isolates. These strains represented a potential application for the production of fermentable sugars from water hyacinth biomass.
Sélection de champignons ligninolytiques producteurs de xylanases isolés à partir d’échantillons provenant de l’Etat de Hidalgo au Mexique
Fragoso Castro Inari Idalith
A l'Université Polytechnique de Pachuca nous disposons d'une collection importante de champignons filamenteux isolés du Huasteca Hidalguense dont les caractéristiques environnementales favorisent la croissance de micro-organismes aux températures plus hautes que le milieu (37ºC). Le maintien de ces champignons a été réalisé au moyen des repiquages périodiques en boîtes de Petri sur un milieu potato dextrose agar (PDA) incubés à 37ºC. La quantification de l'activité xylanase (comme indicateur d'activité hemicellulase) s'est réalisée en utilisant la méthode de Ramesh et al. (2008) en modifiant la source de carbone avec du xylane à 0.2 % et en révélant l'activité enzymatique avec du lugol. On a réalisé un criblage de 60 champignons pour lesquels a été quantifié l'indice de puissance (IP : une relation entre une activité enzymatique et une croissance radiale). Parmi les souches étudiées, 36 souches ont présenté une activité enzymatique et 3 d’entre elles ont été sélectionnées pour leur indice de puissance élevé: Trametes sp. N°46 a présenté un IP de 2.1, suivi de Phanerochaete sp. N°33 avec un IP de 1.7 et Daedalea palisoti n°153 avec un IP de 1.5. Par la suite, les activités enzymatiques xylanase et cellulase ont été quantifiées dans une fermentation en milieu solide en utilisant différentes sources de carbone : xylane, une cellulose et de la biomasse de jacinthe d’eau.
Des progressions dans l'amélioration génétique de Trichoderma
Arana Cuenca Ainhoa
L'expression des gènes impliqués dans la dégradation de polysaccharides (cellulases et hemicellulases) est réglée par un gène nommé XlyR (un gène régulateur de xilanase). Par cela, la sur-expressión de ce gène s'est proposée pour augmenter la capacité du champignon de produire ces enzymes. En collaboration avec à l'UAM-I on a sélectionné un champignon filamenteux, de croissance apicale rapide, capable de sporuler abondamment et de produire une activité xilanasa importante, mais ne produisant pas d’activité cellulase. Pour cela, une souche de Trichoderma a été sélectionnée en tenant compte de toutes les caractéristiques mentionnées. Des cinétiques ont été réalisés pour produire une activité xilanasa en milieu solide pour sélectionner le jour de production maximale et extraire l'ARNm dans le but d’une part d'amplifier et d’autre part de séquencer le gène régulateur du dit micro-organisme. Les cinétiques d'activités enzymatiques se sont réalisées en utilisant différentes sources de carbone : xilane et jacinthe d’eau au préalable prétraité au CSCI, l'Espagne. Pour cela, sur la base de la bibliographie existante des oligosaccharides ont été dessinés et on a mis au point les conditions d'amplification en utilisant la méthode de PCR. Le gène en question sera sur-exprimé dans le même micro-organisme et on vérifiera s’il augmente, sa capacité de produire l'enzyme d'intérêt. Par ailleurs, ce travail constitue la base pour l'analyse d'expression différentielle du champignon sélectionné, cultivé sur la biomasse de la jacinthe d’eau en fermentation en milieu solide. Dans des études préalables nous vérifierons que le kit proposé est capable d’ extraire ARNm de la jacinthe d’eau, sans traitement par ce qu'il interfère à la méthodologie projetée. Pour cette raison, dans le CSIC une extraction de solubles a été réalisée et du matériel a été préparé pour pouvoir faire l'étude.
Production and analysis of fibrolytic extracts by fungi
Loera-Corral Octavio
Water hyacinth comprises a series of complex carbohydrates such cellulose and hemicellulose (mainly xylan), in addition to a minority fraction of lignin. In order to obtain oligomers with increased added valued from those carbohydrates, fungal enzymes are a suitable alternative to modify the polymers. This work describes some features in similar fungal extracts containing those activities required to catalyse the process, with an emphasis in the specificity when the enzymes are produced on the same substrate. Another necessary trait in the extracts to be used on water hyacinth relates to stability which varies depending on the substrate from which the particular enzymes are induced and produced. Some recent findings will be presented in relation to the used of genetically modified strains, which are compatible to current regulations on GMO´s. In a whole these results will be useful in the strategy aimed at the selection of overproducing strains in terms of specific and stable enzymes acting on these carbohydrates. Alternative uses of the water hyacinth will be proposed as a texturizer in solid cultures to obtain spores from entomopathogenic fungi.
Direct quantification of pectinase, xylanase and cellulase activities in Petri dishes assays
Torres-Mancera M. T., Saucedo-Castaneda G., Favela-Torres E., Ramirez-Coronel A. Rodriguez-Serrano G., Roussos S., Gaime-Perraud I
The agar diffusion assay was used to determine the pectinase, xylanase and cellulase activity in Petri dishes. In Petri dishes assays the diameter of the clearing zone around a colony is considered to be an indicator of the pectinase, xylanase and cellulase activity of fungal as well as for bacteria. The aim of this work was to demonstrate that the agar diffusion assay can be used to quantify directly pectinase, bxylanase and cellulase activity using the clearing zone in Petri dishes assays. Assays were realized in
Usages et applications de produits dérivés de la jacinthe d’eau dans la contention et la mitigation d’effets associés aux dispersions pétrolières
Arq. Lorenzo Vargas
Devant la dispersion pétrolière que l'on déplore dans le Golfe du Mexique, il se présentent d'une manière parallèle, des événements mondiaux qui affectent les systèmes environnementaux: économiques et financiers; Ces évènements qui joints au compte d'un surendettement environnemental de l'actuel collapsus d'hydrocarbure dans le Golfe du Mexique projettent des résultats terribles et catastrophiques à un niveau régional. La dimension de cette catastrophe a favorisé des actions désespérées pour contrôler et pour contenir la dispersion de pétrole dans le Golfe du Mexique. Même s'il existe tout une équipe d'experts et d’institutions qui travaillent pour contrôler la fuite d’hydrocarbures, l'un des défis postérieurs sera d’amoindrir les effets de celle-ci. Technologie Spécialisée en Environnement (TEMA) est une entreprise mexicaine qui propose des Technologies avancées axées sur une vaste gamme d'usages et d'applications de la biomasse de la jacinthe d’eau, à partir de laquelle se pourvoient les produits absorbants qui permettent de résoudre des incidents, des dispersions et des fuites de substances industrielles, en particulier du pétrole. Dans le cas de dispersions de pétrole dans la mer, la fibre développée à partir de la biomasse de la jacinthe d’eau peut absorber presque 95 % des hydrocarbures répandu en surface ce qui signifie inverser dans une bonne mesure l'impact environnemental et économique de l'actuel incident. La proposition s'oriente à encapsuler l'hydrocarbure existant dans la mer et vise à contenir la nappe de pétrole. Ainsi cette action évite que la nappe se disperse et par conséquent qu’elle embrasse une plus grande surface.

Critical sites for migratory birds form a vast ecological network; connecting North and South, crossing the outer EU borders. This network of critical sites is becoming more and more fragmented, deteriorating within and especially outside the EU. Western European countries have difficulty in maintaining migratory bird populations (especially going south). There are problems along the flyway in Europe but also in West Africa. This causes problems for all European countries harboring migratory birds in critical sites (Natura 2000 sites, national/ regional protected areas and agricultural land harboring high nature value). If each separate country focuses its policy for maintaining migratory bird populations only on restoration of, and agri-environment for its own critical sites along the flyway, these investments will be inefficient if at the same time other critical sites in other countries along the flyway are deteriorating. Therefore, cooperation along de flyways is necessary for maintaining migratory bird populations. The objectives of the Workshop will be :
- Creating a quick overview of the status of critical sites along the East Atlantic Flyway bearing in mind economic development and the importance of these sites for “European’ migratory birds.
- Sharing different national experiences among relevant organizations on critical site restoration and agri-environment along the flyway in relation to rural development.
- Investigate points of common interest in methods used, points of view, best practices in policy and implementation, regarding critical site restoration and agri-environment.
- Creating a network of policy makers and practitioners for attuned activities on ecological restoration and rural development in each country and sharing knowledge, experience and best practices relevant to this subject.

Many reintroductions have been set up outside of the framework of restoration ecology. However, they face various challenges that have already been identified in this framework. Among them, one of the most important is the lack of agreement on reintroduction success criteria, despite the existence of numerous recommendations and meta-analyses. Restoration ecology already set up a list of success criteria for ecosystem restoration that could provide directions for reintroductions. Indeed, sustainability, resilience and connection clearly remind us that long term population viability is the ultimate goal of these programs. Nevertheless, if all agree that reintroduced populations should be viable, we still need general approaches, targets and threshold to define their success. We propose simple elements that may help to structure these issues and may be widely used among reintroduction programs. First, we distinguish reintroductions run for conservation issues from other programs that, in some cases, may have their own ad hoc criteria. Second, it seems necessary to distinguish between ‘global’ versus ‘local’ conservation targets. In the first case, reintroduction is necessary for the conservation of a globally threatened species. In the second one, reintroduction concerns a species that is not globally threatened. Third, we can split reintroduced population dynamics in three basic phases: settlement, growth and regulation. Their duration may vary and they can even overlap but in each phase, PVA approaches may help to define success criteria accounting for individual and environmental quality. Finally, the ultimate long term success rely on the third phase where IUCN red list criteria for viability may be used at a global or a regional scale according to the type of target previously defined. The workshop will have the following aims:
- The improvement of the connection between reintroduction practices, conservation status and restoration ecology.
- The presentation of new success criteria followed by a wide discussion open to the presentation of alternatives.
- The evaluation of their potential relevance for a wide range of taxa and situations.
- The implication of the criteria for the a priori definition of reintroduction aims and the monitoring of reintroduced populations.
- The proposal of the set up of national and European networks to exchange monitoring information and apply the criteria on a wide range of reintroduction programs, in connection with other initiatives set up at an international level.

For restoration to make a successful bridge between project work and the social/political world outside, we have to excite a wider audience to show ecological restoration can contribute to a richer society. This workshop highlights two unique Millennium projects in Englands North and South West. The Eden Project in Cornwall and the National Wildflower Centre in Liverpool have both shown possible pathways for this to happen, each of which can show by creative means, how the environment can lead in a new kind of restoration. Measurable in many millions of pounds, to the local economies, and by generating local pride in these regions. It addresses the importance of engaging new conversations with a broad spectrum of fields, professions , and social groups, beyond a narrow base of research priorities. Most importantly this workshop will deliver, and present a fun and stimulating consultation, which by vox pop will invite others to share their thoughts and practice of breaking barriers between strict science and the social world outside (this will be done by entertaining short interview and questionnaire during the first two days of the conference. For this reason it is best to stage the workshop towards the end of the conference).These finding will be presented at the workshop, in a creative manner, to ensure topical debate, and be used to produce a statement of social action which will be presented to the SER Europe Committee as a stimulating conference output.

Ramsar’s Scientific and Technical Review Panel (STRP) is currently updating and expanding the existing Ramsar guidance on restoration and rehabilitation of lost or degraded wetlands, in the context of Resolution X.16 on “A Framework for processes of detecting, reporting and responding to change in ecological character, including approaches to prioritization and links with other Ramsar tools and guidance, inter alia those on climate change and on economic values of ecosystem services.” The existing guidance, which is fairly generic, was adopted by resolution of the member parties at COP VIII in 2000. This workshop is planned to be one of several held around the world through 2010 and 2011 that will seek input from various end users including managers and restoration experts, with the final proposal presented for adoption at COP 11 in early 2012. The workshop attendees will first discuss the utility of the existing Ramsar guidance. This will assist in verifying the outcomes previously expressed by the STRP working group. The wetland restoration experts present will then be invited to identify existing guidance on wetland restoration by habitat types, who uses it, does it work, are there any obvious gaps and finally provide good examples of the application of the guidance as case studies. The outputs from the workshop will feed into the proposed updating of Ramsar’s guidance on wetland restoration and rehabilitation
